All of a sudden, out of nowhere, the FPS drops a lot, making the game barely playable. After a few seconds, it comes back again at normal FPS values.
The event is not associated to explosions, number of enemies or projectiles or any particular texture/event/lightning in the game. My computer is able to run BF 2042, COD Vanguard and many other games at ultra specs without any sort of FPS drop.
By the way I'm not using dynamic resolution or dynamic texture scaling (I've disabled them).
